- the projections 11b are caulked by the caulking portions 3c, whereby the second switch 10 is mounted to the DC switch portion 3 of the frame 1.
- an operating rod (not shown) projecting from the second case 11 toward the first switch 5 is formed on the lower surface side of the frame 1. Interlockedly with a sliding motion in the arrow E or F direction of the operating member 7 the operating rod slides and the second switch 10 turns ON and outputs an ON signal upon turning ON of the first switch 5, while upon turning OFF of the first switch 5 the second switch 10 also turns OFF and outputs an OFF signal.

- the switch device S connected to the primary circuit 21 in the electric apparatus embodying the invention has the operating member 7 capable of being operated ON manually and OFF automatically and also has the drive source 12 capable of actuating the operating member 7 automatically to turn OFF the first and second switches 5, 10 automatically.
- the switch device S comprising these components is connected to the primary circuit 21.
- control system circuit 28 when the control system circuit 28 detects an ON or OFF signal outputted from the second switch 10 during ON or OFF operation of the switch device S connected to the primary circuit 21, the control system circuit writes information such as "0" or "1" into a memory (not shown) formed in the same circuit.
- the lock member 8 is positioned away from the locking wall 7d (a solid black portion).
- an ON signal (information of "0") is outputted.
- the control system circuit 28 detects this ON signal, it collates information pre-stored in initialization in the memory of the control system circuit 28, for example, "0" information with the ON signal from the second switch 10, and if both are coincident with each other, the control system circuit rewrites information "0" to "1" in the memory.
- the operation of the electric apparatus can be stopped by operating the switch device S manually or automatically to turn OFF the power supply circuit of the electric apparatus.
- the electric apparatus which is in normal operation can be turned OFF manually in the following manner.
- the lock member 8 positioned in the cam recess 7b is guided by the cam bottom 7c and is disengaged from the locking wall 7d, so that the operating member 7 is unlocked.
- the electric apparatus which is in normal operation can be turned OFF automatically in the following manner.
- the control system circuit 28 detects a control signal issued from a timer installed in the electric apparatus or from a remote controller or the like, electric power is fed to the drive source 12 in accordance with a command issued from the circuit 28, so that the moving core 12a is attracted in the arrow P direction.
- the drive member 13 turns clockwise with the support hole 13c as a center and, as shown in Fig. 6, the cam surface 13b of the drive member 13 is positioned on the locking wall 7d and pushes the lock member 8 upward, whereby the lock member 8 is disengaged from the locking wall 7d and the operating member 7 is unlocked from the locked state.
- the operating member 7 When the operating member 7 is unlocked, the operating member 7 is returned in the arrow E direction by virtue of the resilient member (not shown), the second switch 10 and the first switch 5 are turned OFF automatically in this order, the switch device S reverts to its initial state automatically. Then, the power supply circuit is turned OFF automatically and thus the operation of the electric apparatus can be stopped.
- an OFF signal (information of "1") is outputted and the control system circuit 28 detects this OFF signal and rewrites information from "1" to "0.”
- the supply of electric power to the primary circuit 21 is interrupted and the supply of electric power to the secondary circuit comprising the signal and motor system power supply circuit 23 and the signal system power supply circuit 24 is also interrupted, whereby the consumption of stand-by electric power (cold reserve) can be made zero.
- the power supply of the electric apparatus can again be turned ON normally by operating the switch device S in accordance with the procedure described above to control the control system circuit 28.
- the control system circuit 28 determines that the result is NG and that the ON operation of the switch device S is not in normal condition but in abnormal condition.
- control system circuit 28 determines that the ON operation is in abnormal condition, electric power is fed to the drive source 12 of the switch device S in accordance with a command issued from the control system circuit. Consequently, the drive source 12 is operated, the operating member 7 is unlocked, the second switch 10 and the first switch 5 are turned OFF automatically in this order to cut off the supply of electric power to the primary circuit 21, and the operation of the electric apparatus is stopped automatically. Thus, it is possible to make sure whether any trouble has occurred or not in the electric apparatus during power failure.
- an OFF signal (information of "1") is outputted from the second switch 10 and the control system circuit 28 detects this OFF signal and rewrites the memory contents from information "1" to "0,” thus indicating that the power supply circuit of the electric apparatus has been turned OFF in normal operation.
- the memory contents are rewritten unconditionally when the second switch 10 is OFF, while when the second switch 10 is ON, the memory contents are rewritten on the basis of the result of comparison between the memory contents and the signal provided from the second switch 10.
- the electric apparatus constructed as above is a drying machine for example and upon occurrence of a dangerous act, for example, in the event a child opens the lid and enters the interior of the drying machine when the machine is OFF in an abnormal condition such as power failure, the control system circuit 28 detects a rise from the abnormal condition after restoration and before restart-up of operation of the drying machine and causes the switch device S to operate automatically, thereby making it possible to stop the restart-up of operation of the drying machine.
- control system circuit 28 causes the power supply circuit to turn OFF in an instant and the operation of the electric apparatus can be resumed after making sure if any trouble has occurred or not in the electric apparatus during power failure.
- the switch device has first and second switches and the operating member can be held in a locked state manually and in an unlocked state manually or automatically.
- the first and second switches are turned ON, while when the operating member is unlocked, both switches are turned OFF.
- the supply of electric power to the primary power supply circuit is controlled in accordance with ON/OFF operation of the first switch, and the second switch outputs an ON or OFF signal, which is detected by the control system circuit.
- the first and second switches can be operated ON and OFF simultaneously by operation of the operating member and it is possible to provide an electric apparatus provided with a switch device superior in operability.
- the primary circuit can be turned OFF by the first switch, it is possible to provide an electric apparatus with reduced consumption of stand-by electric power (cold reserve).
- the switch device has a drive source capable of actuating the operating member automatically and thereby turning OFF the first and second switches automatically.
- the second switch can output ON and OFF signals in response to operation of the operating member and these signals are detected by the control system circuit, which in turn rewrites the memory contents at every switch-over between the ON and OFF signals.
- the control system circuit collates the ON signal outputted from the second switch with the contents stored in the memory, and in accordance with the result of this collation the control system circuit makes control to continue the supply of electric power to the primary power supply circuit or causes the drive source to turn OFF the switch device automatically, thereby interrupting the supply of electric power to the primary power supply circuit.
- control system circuit upon restoration from power failure for example, the control system circuit detects a rise from an abnormal condition and makes control to turn OFF the primary circuit automatically, thereby once stopping the operation.
- the operation can be resumed after checking whether any trouble has occurred or not during power failure, thereby permitting the provision of a highly safe electric apparatus.
